2015-08-31 (M) Wrist Mounted Chording Keyboard

Code was written to control two continuous rotation servos attached to a wrist mount. Rather than requiring one of the servos to have the motor leads reversed this code has outputs for two servos. While the servos should always turn synchronously it seemed more important that they can be easily hacked and many guides and tutorials already exist for converting servos to continuous rotation.

Outputs for this code have been written for Arduinos with more than six possible pins like an Arduino Pro Mini but comments were added for anyone wanting to use something smaller like a DigiSpark or one of the knockoffs. In the case of an ATTINY85 board the limit switches were put on pins 3 and 4, the data pins, so the USB programming will still work so long as the switches are both open.
